UNITED STATES PATENT OFFICEo IMPROVEMENT IN FILTERS AND COOLERS.

Specification forming part of Letters Patent N O. 5l ,703, datedDecember 26, 1865.

To all 'whom it may concern:

Be it known that I, WILLIAM P. DICKIN- SON, of the city of Beading, inthe county of Berks and State of Pennsylvania, have invented a new anduseful Improvement in an Apparatus for Filtering and Cooling Vater; andI do hereby declare that the following is a full, clear, and exactdescription of the construction and operation of the same, referencebeing had to the accompanying drawing, and to the letters ot' referencemarked thereon, in Which- A is the supply-pipe connecting with the mainWater-pipe outside, by which the Water is conducted into theilteringchamber. C is a filtering-box fille-d with Washed gravel andcovered with a screen and packing-plate, represented in D with planesperpendicular to the four arms thereof extending to the top of thewater-chamber D, of which K is the cap or top plate. E is theconveying-pipe from D into the cooling-chamber J. F is a waste ordischarge pipe connecting' with the sediment-l chamberB. H is thedrawing-ott' pipe. S is the stop-cock ofthe waste-pipe. rlhe letter mmarks the place for an extra stop-cock in case thepressure of the Wateris light.

The nature ofthe invention consists n the simple method of removing thesediment from the bottom of the apparatus by the peculiar arrangementand combination of the several parts.

The large chambers are made of stoneware pipe, iron pipe, or any othermaterial to suit the pressure of the Water. The two coolers hold aboutforty gallons of Water together, but there may be connected as manycoolers as desired. The Water is first conducted through the supply-pipeA into the filtering-chamber; thence it passes through the n'lteringboxC, leaving behind allimpurities, which settle to the bottom of chamberB. From G the water comes purified into chamber D, whence it isconducted through the pipe E into the cooler J. During` all this timethe Water undergoes a cooling process, and as it is coolest at thebottom the draw-oft pipe H is inserted ,deep into the cooler and thewater drawn from it for use. I

By opening the stop-cock at S the force ot` the Water rushing` throughthe Water-pipe F will carry with it all sediment in the bottom ofchamber B, and if any sediment should accumulate in the bottom of thecooler J the same may be removed by opening the stopcock at G at thesame time With S.

What I claim as my invention islhe arrangement of the sediment-chamberB, ltering-box C, water-chamber D, pipe E, cooling-chamber J,discharge-pipe F, and cocks S and G, as and for the purpose specied.
